in a problem using the Rutherford scattering experiment, i Need to find what the turning distance would be using lead instead of gold. I have that gold has a Q= 79e, what would the Q = ?? for lead?

would this be the constant called k...in the final equation.?? so P = Tk and V = Tk

these books can be very helpful for a lot of these subjects. https://www.amazon.com/dp/0071393072/?tag=pfamazon01-20
